quantum dot

Researchers at MIT have created what could be the flat panel display of the future, combining organic materials with high-performing inorganic nanocrystals to create a hybrid optoelectronic structure. In other words, a quantum dot-organic LED, or light-emitting device. Also called artificial atoms, quantum dots are nanometer-scale “boxes” that selectively hold or release electrons. Unlike traditional LCDs, which must be lit from behind, quantum dots generate their own light. Depending on their size, the dots can be “tuned” to emit any color in the rainbow. And the colors of light they produce are much more saturated than that of other sources.
